To all whom it may concern:

Be it lmown that l, Wninmin lVl. S'rz, a citizen of the United States,and resident of St. Louis and State of Missouri, have invented certainnew and useful Improvements in Distributing-Rollers for Printing-Presses, of which the following is a specifition containing afull-,clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

invention relates to improvements in riding and distributing rollers forprinting presses,wlierein a roller, convertible to con tinuous orscctlonal, is mounted on a shaft, supported in adjustable bearings andreated to the bearings of the form inking rollers in a manner to producerigidity of the press frame and wherein oppositely disand axiallyadjustable cams are secured to the rollers. and operate in conjunctionwith fixed projections on the shaft for vibrating the roller forpurposes of ink distribution.

.My object is to provide a simple and inexpensive ink distributingroller, which may be readily attached to an ordinary press,suoh forinstance as of the Gordon type, and which may be readily converted froma continuous to a sectional roller and which may be employed either as asimple rider or a vibrating distributing roller.

My improvements consist in the novel construction, arrangement andcombination of parts, which will be fully, clearly and concisely setforth in my specification, pointed out in my claims and illustrated bythe accompanying drawings in which,--

Figure l is a plan showing my improved roller and its relation withform" lnking rollers.

Fig. 2 is an elevation of the rollers, as shown in Fig. l.

Fig. 3 is an end elevation of the rollers.

Fig. 4 is a fraental longitudinal sectional elevation showing the camfor axially moving the roller, and v Fig. 5 is a fragmental sectionalelevation, showing the construction of a sectional roller.

Referring to the drawings by numerals,- 5 designates the form inkingrollers which are, or may be of ordinary construction and journaled torotate in saddles 6 secured in a common manner to the frame of thepress, and arrang to be tated by ttion over faces is a bracket an inkedsurface, then over the fo, as

is usual with presses of the Gordon type.

Secured to each saddle and projecting upwardly therefrom, from theiroutside lateral 7 having means, such as the slots 8, for theiradjustments relative to the saddles and formed through the one bracketis a circular hole 9 and the other a non-circular hole 9* arranged toreceive the circular and non-circular ends 10 and id of shaft 11arranged for the support of the riding or distributing roller 12,'whoseperiphery engages each of the form inking rollers 5. in order to preventaxial movement of the shaft ll, in one direction, ll employ a nutll onthe circular end 9' of the shaft and form a hole 13 through itsnon-circular end 9 for the reception of a pin or cotter which nut andpin in their engagement with the brackets, cause the shaft to serve as atie between the saddles and thus overcomethe usual tendency to relativevibrations of the saddles and axial movements of the form inkingrollers.

Formed in the shaft ll adjacent each (lid till

of its ends, is an internally threaded seat arranged to recelve a screwit, preferably provided with a friction roller 15 and which screws serveto secure the riding and distributing roller 12 in place on its shaft.

The roller 12 as shown, is formed tubular, and at each end is internallythreaded to receive the collars 17, rotatably mounted on the shaft andhaving a threaded peripheral portion, for securing in the end of theroller, and a smooth peripheral portion to receive a sleeve 18, whoseouter lateral face 19 is of spiral formation to serve a cam, and whichsleeve is secured against rotation on the collar l? by means of. a screw20.

lit will be obvious that with the sleeves id or cams arranged ontheshaft with their longest projections in diametrically oppositearrangement, the cams in engaging the friction rollers 15, will beaxially moved maximum distances, and by a difi 'erent relativedisposition of the earns the roller may be given any desired axialmovement or held by the cams against axial movement, as when the longestprojection of one cam is arranged diametrically opposite the short estprojection of its companion cam.

it will be obvious further, that by an it'll llltl adjustment of thebrackets supporting the shaft the roller may be shifted to vary itstractional relationship with the form inking rollers.

By reason of the screws holding the friction rollers and the cams, it isobvious that the shaft may be withdrawn from the rollers and that thesame shaft, collars, cams and friction rollers may be employed witheither a continuous or a sectional roller.

In Fig. 5 I show a sectional roller, whose outermost sections have theirouter ends internally threaded in the same manner as the ends of thecontinuous rollers described, but whose inner ends are axially spacedand supported on a collar 21, having the spaced annular flanges 22, andin this connection it is to be understood that this spacing of theflanges 22 is preferably slightly in excess of the maximum axialmovement of the roller, in order to obviate the lapping of one sectionof the roller over an inked surface feeding a second roller sectionwhen,

of course, the job is a multi-color one.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent of the United States, therefor, is

1. An ink distributing means for printing presses, comprising a tubularroller internally threaded at each of its ends, a

collar having a threaded connection at each end of the roller, a camfaced sleeve detachably secured to each collar, a friction roller andmeans for detachably securing the friction roller to the shaft adjacenteach cam sleeve, brackets for the support of said shaft, meansforpreventing rotation of the shaft in said brackets, said bracketsbeing slotted to provide for their being adjustably secured to theirsupports.

2. An ink distributing means for printing presses comprising a pair ofordinary ink rollers, an adjustable shaft mounted above and between saidink rollers, removable friction rollers secured adjacent to the ends ofsaid shaft, an ink distributing roller of less length and diameter thanthe ink rollers revolubly mounted on said shaft, between the frictionrollers,and adjustable therewith, and oppositely disposed removable camfaces carried by the ends of said ink roller and contacting with thefriction rollers.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
